SIGNAL-PRINT FOR CALCULATORS.

Specification of Letters Patent.

Patented May 9, 1916.

To all Iwhom t may concern Be it known that I, JAMES II. DooLnY, acitizen of the United States, and a resident of East Orange, in thecounty of Essex and State of New Jersey, have invented certain new anduseful Improvements in Signal- Prints for Calculators, of which thefollowing is a specilication.

This invention relates to means for pr1nting signal characters orspecial marks in an adding machine adjacent special amounts that areprinted on the record sheet and also to indicate other facts such asthat an item or number has been accumulated, but not printed on therecord.

In a Patent No. 1,092,497, granted April 7, 1914, to J. C. Lotterhand,is set forth and claimed means that upon depression of a special key,will cause, upon subsequent operation of the handle or motor shaft, a.special operation of the machine different from the normal listing andaccumulating of items, and which printing of the signal is effected atonce upon the depression of the special key, and previous to anyoperation or movement whatever of the handle or motor shaft. In suchconstruction a bar is provided that is normally tensioned p and uponinitial depression of one of the keys the bar is released and advancedbysuch ten-- sioned'means aA distance diering according to thekeydepressed. And in suoli construeq -,tion'a further depression of the keycauses ltheswinging of such bar and thereby e'ects .gf-signal device isselected and positioned at .the saidiirst movement. of the`bar by itsthe printing operation of the signal; vwhich Vtensioned device..

Ink the present invention the multiple printing member is connected withmeans that are positively actuated by the depression of one of thespecial keys of the niacliine,'tliat is, is energized and actuated bythe actual depression of 'the key stem, in contra-distinction to thestructure ofthe said patent wherein the positioning means for theprinting member has a spring or by and during the depression of one ofthe special keys. And such operation takes place during the depressionmovement of the key stem, so that by the time the key stem lias beendepressed its full and proper distance, the type carrier is positioned,and the hammer is drawn back to be tensioned and released to make theimpression.

In the accompanying drawings illustrating one embodiment of myinvention, Figure 1 shows a side plate of an adding machine with theparts relating to the present invention connect-ed therewith. Fig. 2 isa plan view partly broken, of the parts shown in Fig. 1. Fig. 3 is aview of the parts shown in Fig. l, with certain members in intermediateposition. Fig. 4: is a side elevation showing the printing hammer andparts connected therewith to operate the same; and Fig. 5 is a rearview, partly broken, of the partsshown in Fig. 1.

The machine as shown is somewhat of the form set forth in the saidpatent to J. C. Lotterhand. The left hand side plate 6 is shown that issuitably supported in upright position. At the rear is suitablysupported a platen 7, to receive impressions from the usual printinghammers of the machine, not shown. Between the hammers and the platenare arranged type carriers that are caused to print on the platen by thehammers. A type carrier 8 having four type 9, 10, 11- and 12 mountedthereon, is suitably supported for vertical movement adjacent theplaten, to bring any one of these four type opposite the platen. Thecarrier 8 has an extension 13 pivoted to one arm 14 of a bent lever14-49 secured to a shaft 15 that swings in the supporting plate of theprinting mechanism, and in the plate 6, and projects out beyond thelatter. This shaft 15 at the outer end is secured to an arm 17 extendingupward and which is pivoted to a bar 18 extending longitudinally outsideof the plate 6. At its front end the bar 18 is supported by a roller 19carried by the plate 6 and engaging a recess in the lower part of thebar. By this means the bar has a limited movement rearward that willswing the arm 17 to rock the shaft 15, and through the bent lever 1awill serve to elevate the type carrier.

In the views are shown four special key stems 20, 21, 9.2 and 23, thatmay represent respectively the total, the sub-total, the noni IOC printand the non-add keys; for example, as set forth in the said patent to J.C. Lotterhand, and in another patent to J C. Lotterhand No. 1,102,157.Each of these key.

stems is shown as provided with a pin, as 24, 25, 26 and 27respectively. The bar 18 is shown as being drawn forward normally by aspring 28 until the carrier 8 is in its lowermost position with itsuppermost type 12 opposite the axis of the platen 7. In the upper edgeof the bar 18 is a recess having a cam or inclined edge 29 that in thenormal position of the bar just described, will lie beneath the pin 27on the stem 23. On depression of this key the pin will strike theinclined edge and force the bar 18 rearwardly, until the pin passesbeyond this cam and into a recess 30 in the bar 18. These parts of thebar are so arranged that the bar will thereby be given a rearwardmovement against the tension of the spring 28, and through arm 17, shaftand arm 14, the carrier will be lifted a maximum distance, so that thelowermost type 9 is now brought to the printing position opposite theplaten. The bar 18 also has a recess 31, at the rear of which is a camor incline 32, arranged to coperate with the pin 26 on the key stem 22.When this latter stem is depressed the bar 18 will move rearwardly fromits normal` forward position, but as will be seen from Fig. 1 the amountof inoline engaged by the pin will be less than that coperating with thepin 27, and hence the bar will move a less distance rearwardly. And thiswill serve to elevate the type carrier 8 sufliciently only to bring thetype 10 to the printing position.V Similarly a recess 33 is provided tocoperate with the pin of the key stem 21, and has a short incline or cam34. l/Vhen the stem 21 is depressed the side bar will travel rearwardlya less distance than caused by either of the said key stems 22 or 23,and the carrier 8 will rise only sufficiently to bring the type 11 tothe printing position. The type carrier 8 in its normal position has thefourth type 12 in the printing position; and this character correspondswith the fourth key 20. Therefore there is no need of shifting the typecarrier on depression of the key stem 20.

A hammer 35 is shown mounted to swing on a suitable pivot 36 to strikeone of the four type respectively in the four described positions of thecarrier 8, and cause the type to make an impression on the platen. Thehammer has a beak 37 on its lo-wer end that isr engaged by a trigger 38,pivotally mounted on one arm 39 of a bent lever, mounted on a fixedpivot 40. Avspring41 is secured to a lug 42 on anV armof the trigger andpresses itagainst the beak 371m its normal position. Butiwhen thebentflever isswung theupperwarrnV thereof causes a movement `bodily ofthe trigger 38, and the latter engaging the hammer will swing it back totension its energizer lever 43. At the further movement of the arm 39the trigger will have its arm 44 brought to engage a fixed pin 45, thatwill swing the trigger on its pivot, to cause it to release the hammer.Thereupon the hammer will be impelled by its energizer lever 43 tostrike a blow on the positioned type in the carrier 8. To actuate thebent lever having the arms 39 and 53 from the depression of the keystems, I pivot a lever 47 on the side bar 18, at 48.

The upright arm 49 of the bent lever 14-49 carries loosely a shaft 50,which shaft extends outwardly and forms the pivot connection between thearm 17 and the bar 18. Vhen the bar 18 moves rearwardly to swing the arm17 and shaft 15, obviously the shaft 50 will be bodily moved to therear. This shaft 50 has an arm 51 secured thereto, that projects forwardand engages a pin 52 on the arm 53 that forms a bent lever with the saidarm 39. A spring 54 serves to draw the arm 53 and parts connectedtherewith downwardly to cause the pin 52 to retain contact with the arm51. At its outer end the shaft 50 is rigidly secured to an arm 55carrying a pin 56, that engages the rear slotted end 57 of the sidelever 47. `The spring 28 is not connected directly to the side bar 18,but to the lever 47 and hence tends to draw its forward end upward thatwill cause it to engage the pin 24 on the total key 20 in the normalposition. When this key stem 2O is depressed the forward end of thelever 47 will move downward and the rear end will swing up and rock thearm 55 and swing the shaft 50. This will swing the arm 51 upward to rockthe bent lever 39-53, and the latter through the trigger 38 will firstretract the hammer and then trip it to make an impression. It will beunderstood that the total key has no connection with the side bar 18that positions the type carrier, and this is because the carrier isnormally held with the type 12 corresponding to the total,V

in the printingposition. The swinging lever 47 on the side bar 18 is soconstructed that it will be engaged by each of the pins 25, 26 and 27 onthe other three key stems when depressed. But the lever 17 is' notengaged by these pins until the pin has first engaged its cooperatingcam edge on the side bar 18 and caused the advance rearward of the bar18, and thereupon the pin moves downward into the recess beyond the cam.At such stage the pin will not cause further rearward movement of thebar 18, but will now and for the first time engage the lever 47 to rockit on the bar 18, thereby causing the trigger to cock and release thehammer.

It ywill Vbe understood thatV at the initialv part of/the depression lof,either one of, these three key stems (except the total), the side bar18 is at once engaged and moved rearwardly, carrying with it the lever47 that is pivoted thereon. Only after the pin on the key stem hascaused the full rearward movement of the side bar 1S, does the pin comeinto engagement with the lever 47. And the continued depression of thekey stem causes the pin to swing the lever 47, to cock and trip thehammer. Vhen the key stem depressed has been released and returned tonormal position, the spring 28 will return the side bar 18 and lever 47to their normal forward position. This spring will also swing the lever47 to its normal position that will return the parts connected therewithfor operation of the trigger. The spring 54 connected with the bentlever 53-39 will swing it back and cause the trigger to re'e'ngage thebeak of the hammer 35.

It will thus be seen that the type carrier is positively actuated ormoved to position the type, from and by the depression of one of thespecial key stems. This is done against the tension of a spring thatwill return the carrier and connected parts to normal position when thekey stem is returned to its normal position. It will also be understoodthat by the actual depression of the key stem, the hammer is first drawnback and energized, and by the continued movement of the key stem thehammer is released to make the impression. The several parts areabsolutely independent of any operation of other parts of the machinefor any movement or resetting whatsoever.
